Marine is a young raccoon that shows sibling-like affection towards Blaze the Cat and Silver the Hedgehog. She is ticked off by Anti-Blaze's antics, as well as upset by them. Marine is in charge of making sure the wedding goes smoothly, according to Princess Sally Acorn.
- Marine plays the role of Twilight Sparkle from MLP:FIM.
- Cream the Rabbit was originally supposed to do this role, but it was changed to Marine due to the relationship with Silver.
- Marine's ears are bigger than they are in Sonic Rush Adventure.
- She appears to be very sensitive, because of how she was annoyed by Silver not telling her about the wedding in person.
